Revealing mistake: In the first scene, when Nicholson is driving to the Overlook, the shadow of a helicopter can be seen at the bottom right. This is only visible in the un-matted VHS print and fullscreen DVD. (00:01:05)
Visible crew/equipment: In the final shot of the opening sequence (before "the Interview" title shot), at the top of the frame, you will see the helicopter blades twirling. (Visible on fullscreen DVD and VHS.) (00:02:43)
Continuity mistake: In the initial overhead shot of the hotel the hedge maze is not there though later on it is shown quite close to the hotel. (00:02:45 - 01:42:30)
Continuity mistake: At the beginning when Danny is talking to his Mom and eating a sandwich, the sandwich gets about 5 bites smaller in a split second. (00:04:45)
Other mistake: When Stuart Ullman is showing Jack and Wendy their quarters, there is a window on the wall to the right across from the bed. However later, when Jack tries to break into the bathroom with the axe and Wendy puts Danny through the window onto the hill of snow, their quarters is not on a corner of the hotel, which the aforementioned window would suggest. (00:22:45)
Continuity mistake: As Danny is writing 'redrum' on the bathroom door, the lampshade on the nightstand light is askew. A moment later, when Jack is knocking down the door with the axe, the lampshade has somehow straightened itself out. (01:32:40)
Continuity mistake: In the beginning when Wendy is talking to the doctor, Wendy lights a cigarette, seconds later the paper has burned almost to the filter.
Continuity mistake: When Wendy is looking through all the typed sheets where Jack has typed 'All work and no play makes Jack a dull boy', you can see that they are getting disorganised, and when Jack sneaks up on her, she gets a fright and puts them down in an untidy pile. However, in the next shot, they are in a relatively neat pile again in the tray.
Continuity mistake: When Danny is playing alone in the corridor, with his toy cars and trucks, in the overhead shot, the little vehicles are set up on the orange and brown pattern, as the ball roles to him down the center brown path in the carpet's sextagon pattern. However, in Danny's close-up, when the ball is in front of him, all the little toy vehicles are now set up (still the same way) on the opposite side of the carpet's distinct pattern, as he also faces the opposite way. This mistake has absolutely nothing to do with the ghosts of The Overlook moving the ball.
Continuity mistake: When Hallorann is showing Wendy & Danny around after they first arrive at the hotel, they walk through the kitchen towards the camera & into the freezer door to the left of the screen. You can see the kitchen still visible in the background. When they leave the freezer (after Hallorann calls Danny "Doc"), the background is completely different & the kitchen is not visible. This is because they have actually filmed a different door on the opposite side of the corridor. They then walk towards camera again & back into the kitchen they have just walked through.
